Question

Which number has a repeating decimal form? A. square root 15 B. 11/25 с. 3/20 D. 2/5

Answer 1

Verify each option

option A

`\sqrt[]{15=}3.87298.\text{.}`

Is not a repeating decimal form

Option B

11/25=0.44

Is not a repeating decimal form

Option C

3/20=0.15

Is not a repeating decimal form

option D

2/6=0.333333333....

Is a repeating decimal form

therefore

answer option D

we know that

a rational number is a number that can be expressed as the quotient or fraction p/q of two integers

so

If we have

`\begin{gathered} 3\sqrt[]{16\text{ }} \\ =3(4) \\ =12 \end{gathered}`

and 12

12=12/1

12=24/2
